Available now from Wilson Combat – The 7.62×40 WT (Wilson Tactical) is an all new powerful .30 caliber cartridge solution for the standard AR-15 rifle platform that is inherently accurate, low recoil and only requires one unique part – a new barrel. The 7.62×40 WT works with all other standard pattern 5.56 AR components and is completely reliable with the new Lancer® L5 AWM magazines as modified by Wilson Combat.
The wide range of available .30 caliber hunting bullets makes the 7.62×40 WT an ideal choice for hunting of medium to large size game with the downrange ballistic performance only a .30 Caliber projectile can deliver. Experienced shooters will be pleased by the match grade accuracy and terminal effectiveness and energy easily exceeding the 7.62×39 Russian, while novice shooters will appreciate the mild recoil and low report. Tactical shooters looking for a hard hitting, fast handling, practical .30 Caliber AR-15 service carbine will find the 7.62×40 WT a viable alternative to the 5.56×45 for self defense and law enforcement applications. With 18/19 or 28/29 round capacity using Wilson Combat modified Lancer® L5 AWM 5.56 magazines, maximum firepower is retained.
The 7.62×40 WT cartridge is based on a standard Lake City 5.56×45 NATO/.223 cartridge case that goes through a simple shortening and reforming operation to achieve appropriate cartridge dimensions. Wilson Combat has reloading dies, case gages, cartridge cases, handload data and a variety of loaded ammunition to fully support this caliber.
A complete lineup of Wilson Combat 7.62×40 WT rifles, uppers and match-grade barrels are also available now. Wilsoncombat.com.
